Novel microwave isolator with embedded structure

Abstract

The invention provides a microwave isolator with embedded structure, comprising a steel-made casing and a pure copper radiator, wherein the pure copper radiator is embedded, by means of fusion welding, onto the steel-made casing with a cavity body to form an integrated structure, the hollow cavity of the steel-made casing is internally provided with a temperature compensation plate, a magnetic circuit plate, a central conductor, a microwave ferrite and a cover board, and the load is welded on the pure copper radiator. The pure copper radiator is welded, in a manner of hot fusion, onto the steel-made casing with the cavity body so that the pure copper radiator and the steel-made casing are integrated with each other to form a housing, which, without the magnetic conductivity thereof being influenced, offers excellent channels of magnetic field to the microwave isolator; the microwave isolator with embedded structure not only includes extremely high strength and integrity, but is also superior to the large-power performance of the steel casing isolator; by integrating the steel-made casing having magnetic conduction effect with the pure copper radiator having excellent thermal conduction effect, the microwave isolator with embedded structure fully ensures the unity of high magnetic permeability and high radiating efficiency of the casing and is worth industry popularization and application.

Description

technical field [0001] The invention relates to a microwave isolator with a novel embedded structure, which belongs to the technical field of wireless communication. Background technique [0002] Existing isolators use a magnetically conductive all-steel shell or an aluminum alloy shell. [0003] The isolator with a magnetically conductive all-steel shell has the advantages of good temperature characteristics, good electrical parameter performance, easy assembly and debugging, and high yield; but at the same time, because of the small thermal conductivity of steel, it has the ability to withstand power, especially reverse power. Minor drawback. [0004] The isolator with aluminum alloy shell has the advantage of being able to withstand large reverse power because the thermal conductivity of aluminum alloy is better than that of steel; and because the aluminum alloy shell is not a magnetic material, the constant magnetic material is generally not used in conjunction with mic...
